Abstract

The device relates to the field of transport engineering, namely to the body structure of a passenger car, in particular to the design of the zone of the lower part of the frame of the wind window of a passenger car. The technical task of the utility model is to improve the vibration comfort of the car by reducing the vibration activity of the wind window. This technical problem is solved by that the body structure in the area of the lower part of the windshield frame, including the upper front flap amplifier with a flange for installing and attaching glass to it a window that is inseparably connected to the extension of the front flap shield, in particular by spot welding, while along the length of the interface flange it additionally includes a washer reservoir bracket, a connector, a wiper bracket, an amplifier for fastening the cross member of the instrument panel. 7 ill.

Description

The device relates to the field of transport engineering, namely to the body structure of a car, in particular to the design of the zone of the lower part of the frame of the wind window of a car.

The prior art design of the body connection in the area of the lower part of the wind window frame (LADA 2190 car. Catalog of parts and assembly units. In Russian, English, French and Spanish ”, authors: Sabanov Yu.V. et al., Developer. DTR OJSC AVTOVAZ, AVTOVAZ-TOGLIATTI-RUSSIА, 2012, M240, pp. 330-331), including an upper front panel amplifier with a flange for installing and attaching a windshield glass to it, inextricably connected to the front panel extension, in particular contact spot welding. The design of this zone should provide high local dynamic stiffness of the glass windshield interface of a passenger car. This is due not only to the presence of a vibroactive mass of glass, but also to the fact that the lower part of the wind window frame separates the passenger compartment from the engine compartment of a passenger car.

The disadvantage of this part of the design is its lack of dynamic stiffness, which is due to the reduced natural frequency of the lower part of the windshield frame, and as a result of the reduced natural frequency of the windshield in the car, which leads to unsatisfactory requirements for vibroacoustics.

The technical task of the utility model is to improve the vibration comfort of the car by reducing the vibration activity of the wind window.

The specified technical problem is solved due to the fact that the body structure in the area of the lower part of the windshield frame, including the upper front flap amplifier with a flange for installing and attaching the windshield glass to it, is one-piece connected to the front flap extension, in particular by spot welding characterized in that, over the length of the interface flange, it additionally includes a washer reservoir bracket, a connector, a wiper bracket, an amplifier for fastening the cross member of the instrument panel.

Comparison of the claimed technical solution with the prior art in scientific, technical and patent documentation on the priority date in the main and related sections shows that the set of essential features of the proposed solution was not previously known, therefore, it meets the patentability condition of “novelty”.

The proposed technical method is robust, feasible and reproducible, therefore, meets the patentability condition "industrial applicability".

The essence of the utility model is illustrated in the following graphic materials:

FIG. 1 - interface for installing and fixing, in our case, by gluing, windshield glass in the back of a car, general view;

FIG. 2 - fixing device, general view;

FIG. 3 - explosion diagram of the design of the zone of the lower part of the frame of the wind window of a passenger car;

FIG. 4 is a view of the bracket of the washer reservoir relative to the interface flange and the extension of the front flap;

FIG. 5 is a view of the connector relative to the interface flange and extension of the front flap

FIG. 6 is a view of a wiper arm relative to an interface flange and an extension of a front flap;

FIG. 7 is a view of an amplifier for mounting a cross member of a dashboard relative to an interface flange and an extension of a front flap.

The interface for installing and fixing, in our case, the gluing of the windshield glass in the car body, is formed by the flange 1 of the panel of the windshield frame 7, which is rigidly connected, in our case, by welding, with the extension of the front panel 6 Technical solution of the identified shortcoming - insufficient dynamic the stiffness of the zone of the lower frame of the windshield of the car body, leading to unsatisfactory requirements for vibroacoustics in the passenger compartment, is as follows. Over the length of the interface flange 1 of the panel of the frame 7 of the wind window, the body is reinforced in four places: the washer reservoir bracket 2, the connector 3, the wiper bracket 4, the dash panel mount bracket 5, while the washer reservoir 2 bracket, wiper bracket 4 and the crossbar mount bracket dashboards 5 additionally serve as interfaces for the nodes of the box air intake into the passenger compartment.

The technical result of using the proposed technical solution is to reduce the vibration activity of the wind window, which can improve the vibration comfort of the car.

Claims (1)

The body structure in the area of the lower part of the windshield frame, including the upper front panel amplifier with an interface flange for installing and attaching a windshield glass to it, is one-piece connected to the front panel extension, characterized in that it also includes a washer reservoir bracket over the length of the interface flange, connector, wiper bracket, amplifier for fastening the cross member of the instrument panel.
